I haven’t used them yet, but read a bit about them, too. It is my understanding that Boyhood and Beyond is moral based teachings, then Created for work is working for the Glory of G-d.
For me, I’m going to read Boyhood and Beyond first, since it seems to be a moral grounding book then the “…Work” book; being a natural extension after having a devotion on moral grounding.
Also, most of what I’ve seen the age part was higher for n”…Work”, than for “…Beyond”.
HTH, but keep in mind, I haven’t read them yet. Hopefully someone who has used them will chime in!
